Well I have decided I need more power again. Currently running comp 280h with 1:6 full roller rockers. Thinking I'd like to switch to a solid lifter cam in my stock bottom 406. Any ideas? I'm running jegs aluminum 195cc heads with 64cc chambers. Thanks Mike

Knew it asked before couldn't find thread. wonder if theres newer stuff out. now. I really thought once I got the heads and intake swapped Id be happy but just need more now.

I don´t think theres much newer stuff for gen1 than what was couple years ago. That´s ok. What´s your final compression after head swap? rpm you want for peak power? what kind of exhaust system? Trans/ rear gears?

that stock bottom end....

is going to be the limiting factor in more HP.
oh, it will make more power, but they are known for NOT living when exposed to 6500+ rpm.
which is where a bigger cam will work best.
if it were me, I save for a little M block with 421/ 434 kit and step up safely! and BOLDLY!

call the cam company of your choice. getting cam advise from anyone on the internet is not a good idea. I know many engine builders that wont even make their own cam choice. call the experts.

If its a speeder I still love the sound of a Duntov 30-30. I will turn all the rpm your stock bottom wants. I have yet to find an aftermarket cam that I like as much.

Before purchase

Decide if you intend to disassemble the engine to change your piston to valve clearance and compression ratios if necessary .
